Description

[Detailed description of the invention]

The present invention relates to toilet litter for pets, and more specifically, the present invention relates to toilet litter for pets, and more specifically, it is an in-water litter obtained by finely pulverizing minerals with good water absorption, kneading with water or water and desired additives, granulating, and drying. The present invention relates to litter for pets, which is characterized in that it easily disintegrates into fine powder when thrown into water. Conventionally, toilet litter for pets has mainly been made by crushing natural zeolite into particles with an average diameter of about 0.5 to 1.5 mm, 1 to 3 mm, or 3 to 5 mm, depending on the type of pet. Natural zeolite has excellent water absorption and gas adsorption properties, so when used as litter for pets kept indoors, it is convenient because it absorbs water well and adsorbs bad odors relatively well. However, as mentioned above, toilet litter made by simply crushing natural zeolite to a particle size suitable for the type of pet has the following drawbacks. (i) Because it is a mineral, it cannot be disposed of together with general plastic waste at households. (ii) Even when disposed of as non-combustible waste, it produces a foul odor, attracts flies, etc., and is unclean. (iii) Flushing toilets cannot be flushed because the pipes become clogged. As a substitute for pet litter that compensates for the drawbacks of crushed zeolite sand and can be flushed down the toilet, products made from crumpled paper are commercially available. However, this paper does not have the gas adsorption properties of zeolite, is expensive, and has disadvantages such as the fact that the paper sticks to the soles of the pet's feet, making the pet dislike using it. In addition, when producing toilet sand with the particle size as described above depending on the type of PET, for example, the mineral is crushed and then sieved to adjust the particle size, but at that time a considerable amount of unnecessary fine sand is always produced. However, the disadvantage is that it leads to higher manufacturing costs. The present invention has been made to overcome the drawbacks of the conventional pet litter or its substitutes. An object of the present invention is to provide pet litter with good water absorption properties. Another object of the present invention is to provide pet litter with excellent deodorizing properties. It is also an object of the present invention to provide a pellet litter that quickly becomes pulverized when thrown into water and can therefore be disposed of in a flush toilet or the like. Yet another object of the present invention is to provide a hygienic pet litter containing a disinfectant. Another object of the present invention is to provide a pet litter that contains a fragrance and is capable of masking malodors. Yet another object of the present invention is to provide an inexpensive pet litter. In the present invention, the term "pet" refers to pets that are generally pet at home, especially indoors, such as dogs, cats, rabbits, squirrels, hamsters, rats, etc.
This includes small animals such as birds. Toilet litter for pets of the present invention is made by finely pulverizing highly water-absorbing minerals to approximately 50 mesh or less, preferably 200 mesh or less, adding water or water and a small amount of a binder, kneading, granulating, and drying. After that, a solution of bromocinnamaldehyde (hereinafter referred to as BCA) is sprayed and dried, or the finely ground mineral is
It is obtained by adding BCA and water or water and a small amount of binder, kneading, granulating, and drying. The toilet litter of the present invention can be easily produced by granulating the granules into a suitable shape and size, for example, an average diameter of about 0.1 to 10 mm, using a granulator or the like, and drying the granules. Examples of water-absorbing minerals used in the present invention include natural zeolite, synthetic zeolite, clay, bentonite, volcanic ash, Kanuma soil, silica gel, and alumina. Among these, natural zeolite is a particularly preferred mineral because it has gas adsorption properties and is inexpensive. Furthermore, in order to improve gas adsorption properties, activated carbon or the like may be used in combination. Granulation is performed using water or water and a binder. Generally, when using clay-rich minerals, it is not necessary to use a binder. When using minerals with little clay, a water-soluble binder,
For example, CMC, PVA, etc. may be added in an amount of 10% or less based on the mineral. Moreover, a mineral with a high clay content and a mineral with a low clay content may be mixed and used. In the present invention, fragrances, colorants,
Deodorants and the like can be added. These may be added and mixed during granulation, or after granulation,
A solution or emulsion of these additives in an organic solvent such as alcohol, toluene, xylene, acetone, etc. may be sprayed onto the particles. Since the pet litter of the present invention produced as described above disintegrates into fine powder virtually instantly in water, there is no risk of clogging pipes even if it is flushed into a flush toilet or the like. In addition, it is inexpensive because you can scoop up and discard only the parts contaminated by pets.
It's convenient. Furthermore, the toilet sand of the present invention is porous and has a large surface area because it is made by adding water to fine mineral powder, kneading it, and drying it, compared to conventional toilet sand that is made by simply crushing zeolite to the particle size used. . Therefore, its water absorption rate and gas adsorption ability are extremely excellent. In addition, the toilet litter of the present invention, which is obtained by adding and granulating a low-toxicity bactericidal agent or applying it by spraying after granulation, can be used at a time when pet filth rots in a short period of time and releases a bad odor. It is very preferable to use it in a local area because the progress of these rots will be extremely slow. If an appropriate odor is added as a masking agent, the odor of the filth itself and the odor caused by decomposition can be alleviated. In addition, since all minerals are completely pulverized and then granulated to the required particle size, 100% of the minerals can be used, which has great economic significance. Next, the present invention will be further explained with reference to Examples. Reference example 1 Add 450 ml of water to 1000 g of natural zeolite (trade name: Iwami Light) that has been finely ground to 300 mesh or less, knead it in a kneader for 10 minutes, and then apply it to a granulator to form a 5 mm x
It was granulated to a size of 3 mm and air-dried (Sample A). Toilet litter was obtained in the same manner except that 7.5% sodium silicate was added as a binder to the zeolite (Sample B). Water absorption was tested by taking 5 g each of the above toilet sand and commercially available toilet sand (using natural zeolite), immersing them in water, taking them out just before they disintegrated, and measuring their weight. The results are shown in the table below.

[Table] It can be seen that the reference example toilet sand absorbs a large amount of water in a short period of time compared to commercially available toilet sand. Reference Example 2 The disintegration time in water of samples granulated as in Reference Example 1 by adding predetermined amounts of various binders to zeolite finely ground to 300 mesh or less was measured. The results are shown in the table below.

[Table] Example 1 Add 0.8% bactericide BCA to 100g of zeolite from Reference Example 1
20 ml of xylene solution and 25 ml of water were added, and kneaded and granulated in the same manner. When this was used as litter for cats and hamsters, they did not dislike it and used it well, and there was very little odor. Reference Example 3 To 100 g of the zeolite of Reference Example 1, add 10 ml of Fragrance Freshener 47006/E 0.2% ethanol solution and
35 ml was added and granulated in the same manner. Similar to Example 1, when used as litter for cats and hamsters, they did not mind and used it well, and there was little odor. When flushed down the flush toilet, it quickly disintegrated into fine particles and clogged pipes. Nothing like that happened. Example 2 Sample A obtained in Reference Example 1 was sterilized with sterilizer A.
Sprayed with 20ml of BCA0.8% xylene solution, Fragrance Freshener 47006/E0.2% ethanol solution
10ml sprayed and 20ml disinfectant and 10ml fragrance.
After drying, each spray was used as litter for cats and hamsters. The same results as in Reference Example 3 were obtained. Example 3 300% natural zeolite (trade name Iwamilight)
Finely pulverize to a pulp and add a fungicide BCA (bromuscinnamaldehyde) solution and water to it.
Knead and granulate in the same manner as Reference Example 1 to make 5mmφ×10~13
mm toilet sand (containing 0.1% BCA) was produced. This litter was placed in a commercially available plastic pet litter box (40 x 50 x 20 cm (height)) and allowed to be used by a Persian cat. Even after continuous use for two weeks, no bad odor was generated. On the other hand, when commercially available zeolite was used as it was, the bad odor became so bad that it became necessary to replace the sand after 4 days.
